EDIT:

Hmm.

solved this problem.

It is possible to use some objects as obstacles without creating NavMesh on top it?

Dynamic obstacles does not suit me, because they have cylindrical shape

Increasing “Region Min Size” helps in some cases,

but NavMesh still exists on walls

NavArea with ID = 0 allow cut unnecessary parts of NavMesh
